This data comes from the IDL compiler. The format is specified here:
http://msdn.microsoft.com/en-us/library/aa379131(VS.85).aspx.
If the IDL compiler tries to put RPC_FC_ERROR_STATUS_T into the type
nibble then it is buggy. MIDL refuses to do so:
.\test.idl(66) : error MIDL2072 : inapplicable attribute : [range] [
Type 'error_status_t' ( Parameter 'l' ) ]
